Title: Spot-suppression cct for TV - has diode preventing capacitor discharging and applying neg. potential to Wehnett electrode
IPC: H04N3/20
Filed: 1972-07-19
Abstract: The spot-suppression circuit, for a television tube, has the line transformer's output winding earthed at one end and coupled at the other over a diode to the junction between an earthed capacitor and a potentiometer. The potentiometer is coupled via a zener diode to the positive supply, and by its slider to the television tube's Wehnelt electrode. The capacitor is prevented from discharging its negative charge by the diode, and therefore applies a negative potential to the Wehnelt electrode which then blocks the tube, i.e. suppresses the screen spot. The circuit is almost completely independent of the switching off time of the woring voltage.

Title: Transistor amplifier with overload protection - adjusts stabilised input level following fault via cct. with low hysteresis against overcontrol
IPC: G05F1/573
Filed: 1972-07-24
Abstract: The protection applies particularly to transistorised transmitter amplifiers in carrier frequency lines. The stabilised power supply (US) for the transmitter (SV) is provided by a controller (S2) and reference (SG) together with an overload protection circuit comprising a measuring resistor (MW) and time delayed trigger (Zd, Tr, Z2, S1) to reduce the stabilised voltage to zero in event of a fault. The level detector (B), checking the supply to the transmitter input (E) reduces the set level, should the supply collapse, and does not restore full set level until the voltage has again risen to the normal value. The arrangement serves to restore the transmitter to the condition existing prior to the fault. The circuit contains a setting transistor with a series measuring resistor and a Schmitt trigger. The D.C. at the resistor is used as the circuit criterion.

Abstract: PROBLEM TO BE SOLVED: To improve reliability on information by a method wherein each variable feed amount regulating means inquires of an air-condition control device about the presence of a given status, when the given status is present, a message is simultaneously transmitted to the air-conditioning control device, and based on the receiving state of the message, a total status is produced by the air-conditioning control device. SOLUTION: An air-conditioning control device simultaneously inquires of each VAV control unit about the presence of deficiency in a static pressure. After a lapse of a given time, simultaneous inquiry about the presence of property is effected. When an answer to first inquiry is effected, the air-conditioning control device decides that information on excess and deficiency is deficiency in a static pressure. When no answer to first inquiry is effected but an answer to subsequent inquiry is effected, information on static pressure excess and deficiency is decided to be proper. When neither answer to the first inquiry is effected and nor answer to the subsequent inquiry is made, information on static pressure excess and deficiency is decided to be static pressure excess.  The air-conditioning device controls rotation of an air-conditioner fan based on produced information on static pressure excess and deficiency.

Abstract: A sigma-delta modulator (50, 100) attenuates a frequency domain characteristic of a feedback signal to a first stage (60) of the modulator (50, 100) near fS/2, where fS is the modulator's (50, 100) clock frequency. The modulator (50, 100) thus virtually eliminates in-band tones which are characteristic of known sigma-delta modulators, without complex dithering schemes. In one embodiment, the sigma-delta modulator (50, 100) includes a two-tap finite impulse response (FIR) filter (80) within a feedback loop of the modulator (50, 100). The two-tap FIR filter (80) smoothes transitions at an output of a second stage (70) to provide the feedback signal to the first stage (60). This architecture is useful for either a digital-to-analog sigma-delta modulator (50) or an analog-to-digital sigma-delta modulator (100). <IMAGE>
